Vision Resort is a five-star resort and spa founded in 2012. Vision believes in offering authentic services to every customer by fulfilling and catering the needs of their guests efficiently. Facilities and services include spacious rooms, banquet halls, gardens, restaurants, a wide range of food with delicious cuisines. All its employees are well trained and provide high customer satisfaction.
Vision resort focuses on premium pricing strategy for its products as they cater to high profile business class and upper class of the society. The value provided through the luxurious experience to the customers during their stay in the resort and the first class royal service explains the high prices of the resort packages. However, in light of the current economic condition in the world due to the Coronavirus, the resort is currently trying to provide a combination of high quality and service while also providing fair prices.
Also, Vision resort is the owner and operator of the franchise system. They are present in 20 countries prominent ones being in Bahrain, Oman, Kuwait, and Dubai Chicago, Hong Kong, Manila, Mumbai, San Francisco, and Tokyo. It is noteworthy that the prices of the resort packages differ based on the geographic location. Also, prices fluctuate during different times of the year, as they tend to increase during the weekends and Eid holidays and decrease during the low seasons.
Regarding the promotion strategy, vision resort has built and maintained positive awareness, and brand value by word of mouth. This has been achieved by gaining high customer satisfaction and providing excellent customer relationship management. They reward loyalty to regular clients by their signature membership cards known as Vision Gold Passport accepted globally which fetches them extra discounts and additional perks. Due to the social distancing, vision resort adopted advertising via TV broadcasting. Moreover, digital marketing tools such as instagram sponsorship allowed reaching target customers through a click of a button.
Recently, a new global disease has spread rapidly among people and the resort decided to open its doors to the passengers arriving into the country by air and border crossings and were taken to stay for free in a 14-day coronavirus quarantine. This initiative shows the social responsibility that the resort holds towards the community.

Answer the following questions:
1. What is the major pricing strategy vision resort follows and why?
2. What is the price elasticity of demand for rooms in the resort and why?
3. What is the price adjustment strategy followed by the resort management?
4. Give examples of the promotion mix?
5. The hotel resort management is planning to open a new shop in the resort, a brain storming session was held with the hotel employees where they suggested the following ideas: A coffee shop, diving equipment shop, gifts shop. Explain the process (steps) undertaken by the resort management to introduce a new product.

1) Use Euler's method to obtain a four-decimal approximation of the indicated value. Carry out the recursion of (3) in Section 2.6

y_{n + 1} = y_n + hf(x_n, y_n)        (3)

by hand, first using h = 0.1 and then using h = 0.05.

y' = 2x − 3y + 1, y(1) = 4;   y(1.2)

2)Use Euler's method to obtain a four-decimal approximation of the indicated value. Carry out the recursion of the equation

y_{n + 1} = y_n + hf(x_n, y_n)

by hand, first using h = 0.1 and then using h = 0.05.

y' = x + y², y(0) = 0;   y(0.2)

3) Use a numerical solver and Euler's method to obtain a four-decimal approximation of the indicated value. First use

h = 0.1 and then use h = 0.05.

y' = e^−y, y(0) = 0;   y(0.5)

Construct the confidence interval for the population mean μ.

A 98 % confidence interval for μ IS (____,_____)

(Round to two decimal places as needed.)

Chloropropionic acid, ClCH2CH2COOH is a weak monoprotic acid with Ka= 7.94 x 10-5 M. Calculate the pH at the equivalence point in a titration 24.1 mL of 1.33 M chloropropionic acid with 0.3 M KOH.

Write the matlab command to sample the following signals at nyquist frequency

1.x(t)=3cos(2*pi(400)t +0.3*pi)

2.x(t)=cos^2(300*pi*t)

Convert: a. Thermal conductivity value of 0.3 Btu/(h ft oF) to W/(m oC).

b. Surface heat transfer coefficient value of 105 Btu/(h ft^2 oF) to W/(m^2 oC)

Consider the following scenario analysis:

Assume a portfolio with weights of 0.60 in stocks and 0.40 in bonds.

a. What is the rate of return on the portfolio in each scenario? (Enter your answer as a percent rounded to 1 decimal place.)

b. What are the expected rate of return and standard deviation of the portfolio? (Do not round intermediate calculations. Enter your answer as a percent rounded to 2 decimal places.)

c. Would you prefer to invest in the portfolio, in stocks only, or in bonds only? Explain the benefit of diversification.

Based on fossil evidence, it appears that the original population of Furred Zee-s split, where a subset of the population moved towards the south and became isolated after an earthquake created a large rift through the continent The southern Zee population evolved over time to have significantly less fur that the original population and have been considered a separate species (Naked Zee-s)). A few of the fossil organisms have indications of fur, suggesting that the ancestral state was furred

Three small groups then fragmented from the Furred Zee population and colonized three islands (I1, I2, I3) . Islands 1 and 2 are very similar to each other in size and vegetation but Island 3 is significantly smaller. Island 3 cannot support the same population size as the other islands and that results in close genetic relatives breeding with each other.

Two fur color morphs exist in the Furred Zee populations, green and brown. The colors are a result of two different alleles: G (green); B (brown). The brown homozygotes and the heterozygote (BG) both produce brown fur. But a mutation in the Island 3 population resulted in the appearance of another fur color: purple (P). The allele frequencies vary based on location

1. Has evolution occurred between the original population and the island populations? Explain why/why not. (4 pts) Please elaborate

Problem 13-11 (Algorithmic)

Following is the payoff table for the Pittsburgh Development Corporation (PDC) Condominium Project. Amounts are in millions of dollars.

Suppose PDC is optimistic about the potential for the luxury high-rise condominium complex and that this optimism leads to an initial subjective probability assessment of 0.8 that demand will be strong (S₁) and a corresponding probability of 0.2 that demand will be weak (S₂). Assume the decision alternative to build the large condominium complex was found to be optimal using the expected value approach. Also, a sensitivity analysis was conducted for the payoffs associated with this decision alternative. It was found that the large complex remained optimal as long as the payoff for the strong demand was greater than or equal to $16 million and as long as the payoff for the weak demand was greater than or equal to -$29 million.

1. Consider the medium complex decision. How much could the payoff under strong demand increase and still keep decision alternative d₃ the optimal solution? If required, round your answer to two decimal places.
   
   The payoff for the medium complex under strong demand remains less than or equal to $ ___?___ million, the large complex remains the best decision.
   
2. Consider the small complex decision. How much could the payoff under strong demand increase and still keep decision alternative d₃ the optimal solution? If required, round your answer to two decimal places.
   
   The payoff for the small complex under strong demand remains less than or equal to $ ___?___ million, the large complex remains the best decision.
